It's not always easy to nurture plants so they grow and thrive, but it's especially difficult without land -- and gravity. Farming in space isn't exactly a common activity, but if any significant number of people are going to live in space for longer than a few months (without re-supply cargo ships or huge stores of packaged food), astronauts are going to need to figure out how to grow their meals. Space station residents have only just started to eat plants they've grown in space, so it'll be awhile before anyone is growing potatoes on Mars.
